Forward-link rescue synchronization method and apparatus
First Claim
1. In a system comprising a network and at least one mobile station (MS) for enabling communications with the at least one MS, the network including one or more base stations (BSs) capable of transmitting a rescue channel to a MS having a connection with the network that has become a potentially failing connection for assisting in rescuing the connection, a method for synchronizing transmission of the rescue channel with MS attempts at receiving the rescue channel to increase a likelihood that the MS will receive the rescue channel and assist in rescuing the connection, the method comprising:
- transmitting the rescue channel from one or more BSs at a time during each of one or more SUPER_ATTEMPT time intervals;
configuring the MS to attempt to receive the rescue channel from the one or more BSs during each of one or more SUB_ATTEMPT periods, wherein a predetermined number of SUB_ATTEMPT periods are contained in one SUPER_ATTEMPT time interval; and
coordinating the transmission of the rescue channel from the one or more BSs with the MS configurations to increase the likelihood that the MS is configured to receive the rescue channel from a particular BS at a time when the particular BS is transmitting the rescue channel.

Abstract
A method and apparatus are disclosed for efficiently synchronizing the transmission and reception of the rescue channel from the network and to the failing MS, respectively, to communicate the rescue channel to the failing MS and rescue the connection. The cycling through of BSs by the MS and the network is preferably coordinated according to a certain set of strategies to guarantee some transmission overlap for at least a predetermined number of frames, and therefore permit a rescue. To improve the efficiency of rescue, in embodiments of the present invention the MS can execute a more sophisticated detection scheme to determine which BSs are actually transmitting a good rescue channel. This scheme includes a combined detection component and a learning progression component.
